11 years coming up this spring. And in many different full size operations...and actually never been on a micro scale(6x4 was my smallest garden)
How is it clear???? and why is it working??? what does high mean??...what does low mean?...things you don't have answers to...but the answers exist and explain the effects you are seeing. The answer will more than likely come down to the µmols that the canopy is receiving based on the height.
Too high really means that there is not enough intensity...
Too low really means there inis too much intensity and/or not enough coverage...
Neither of which do the heights matter per say... height is just a way you can adjust those actual factors.
People ask me all the time why my lights are so high...well that is because the provide the correct intensity and coverage at that height. Close...far...what ever you want to call it...the fact is it provides the correct µmols...and the height is not very important as long as the coverage is there...and for me it is. Moving it closer will not have a positive effect and nor will farther way...because it's already in the ideal range.
So when people tell me to drop my lights because they run their hps low...well their hps has to be that low to get the numbers I can get farther away with leds and lenses. Plus with mine being farther, has the better penetration potential*. As well as spectral blending when using mono additions to whites. But with no lenses you have to be "lower" to get the same intensity and in turn effect(the growth from high intensity light).
If anything I believe that the higher you can hang lights and get the intensity required is the better they will perform.
I mean this with all do respect to "your position here in the forums"...Yes you are new...3 months ago you were looking into adding an ion8, a couple weeks ago you thought your vero's were running 50% efficient...now you are recommending DIY to everyone and their brother...which is fine, but I would suggest sitting back and taking it all in slower and actually getting some solid grows under it...or even just one...before going as hardcore as you have been recently.
@SomeGuy... I really think that if you had more plant mass in there...like same thing, but 15"-20" of canopy depth...that you would not have had too much light for the space...but for the plants that were in that grow, yes it was more than they needed. But you did killer regardless. For reference...I only got .8g/w on my drone first round...and that was with a generous lack of trimming.
